Be it l nown that we, CHARLES T.

Tiioursos', residing at The Rittenhousc, Twenty- Seoond :i-nd Chestnut streets, in the city oi; Philadelphia and State of Pennsylvania, and Fuss l. Mrrcunm, residing at Laurel Springs, in the county of Camden and State oi New Jersey, citizens ol the United States, have rte-d cort in new and useful 1m provcnicn in C .ll-(flluhs, of which the followlng is :1 specificsiion, reference being haul m coinpunying drawings.

to t is fluiinvention relates to on improved golfclub by which the construction is simplified, the resiliency of the driviugd'cce increased, the elastic force of the blow' *strcngthemed, snrl the durability ol the?cluh improved.

According to our invelltion thc head of the goli cluli is outdo of o shell of metal, profs? ably aluminium, which is ilillod with u resilient substance or substances molded within it while in 1. plastic state, with exposure of the face of the resilient material to form the driving or impact surface of the club and with provision. of irregularities or apertures in. the shell, whereby yielding or dislodgment oi its resilient interior or any part of it is prevented.

Our invention is tions of detail in its up uible of many vsrid ion; but so how: and will (lQSGIlllG K illustrated in Uh army-rugs three preferred terms in which we embody the invention, with the understanding that although subject to the limitations expressed in the claims our invention is not limited to the precise embodiments shown. i

in the accompanying drawings, Figure 1 represents the head of c golf-club constructed so to embody a. preferred form of our invention. Fi s. H and III are respectively vertical and iorizontel sections of the some along the lines 11 11,111 Ill in Fig.1. Figs. 1V and V are similar sections taken along the some lines, but embodying a variation in the, construct-ion of our club. l VI and VII are similar sections'teken along the some lines and embodying another variation in the construction of our club.

We will first describe our invention as e111- bodied in the form shown in Figs. 1, I1, and

The head of the club is formed of a metal l l l l l is of the usual configuration oi the head of a golfidrivor, and is neck for attachment of the stick to form the handle of the club. The casting is preferably of aluminium or other light metal. It is hollow, the preferred thickness of the incssing shell of metal being indicated in the drew- 6o lugs. The casting: is form the six 1hr lflil with which At the buck cl large opening 3 is provided, oi the shape indicated upon the sectional drawings. The shell is further provided with holes or a ortures prcfcrooly circular, of which t ere are a. number piercing surfaces of the entirely :ut away to i lace oi the head, as shown at exposing at ll: 3 point the resilient matethe jinetullic shell 18 filled.

The material is then closely trimmed to the outer surface of the casting both to form a front and back face 2 and 3 and wherever it protrudes through the aper- 9 5 The club is thus completed and ready tures.

for use.

In the variety Figs. IV and V of our invention disclosed in the details of construction are the same as so for specified, With the ex- :00

'ccption that the large openin 3- upon the back of the club is omitted and two or three smaller apertures t are provided in place thereof.

In the variety casting 1 of the shape shown in Fig. l, which Figs. VI and VII the more difference occurs provided with o pierced the hood of the club another the top and bottom turc 6 pierces the casting from near the edge 7 5 LLl there inserted a niass'of plastic mate- 8o or other simiof our invention disclosed in that all of the a ertures 4 are omitted and in place thereof t e interior surfaces of the shell above and below are provided with pro jecti'ens or corrugations 7. The apertures 5 5 around the sides arereduced in number, some of them being replaced by internal projections'S. The aperture or channel 6 is employed as before. In this instance when the resilient material is introduced into the casting under pressure in its plastic condition it reaches into the spaces between the )rojec tions or corrugations and is similarly held in place or bound to the shell as when it-enters the apertureswhich are provided in the con.
